2018 HYUNDAI TUCSON — Complaint #2134923
Open-data reference.
NHTSA Complaint about VEHICLE SPEED CONTROL filed September 29, 2025
NHTSA complaint #2134923 (ODI reference 11690365) concerns a 2018 HYUNDAI TUCSON and was filed on September 29, 2025. The owner reports the failure occurred on April 9, 2024. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as vehicle speed control, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same HYUNDAI TUCSON cohort independently describe similar vehicle speed control failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2018 HYUNDAI TUCSON shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
Van Hyundai Dealership in Carrollton, TX has confirmed excessive oil consumption causing catalytic converter failure that results in the engine stalling and unable to accelerate. Weâve already replaced the catalytic converter once in 2024 because it was full of oil and causing engine failure. Less than a year later (less than 10,500 miles) the same problem was reproduced. The dealership refuses to replace our engine due to the engine defect. This problem directly impacts the engines ability to perform, unable to accelerate on the interstate, and engine stalling which directly impacts our safety and puts our family into a life threatening situation when the engine fails on the highway. The engine has a defect that Hyundai refuses to address. There are no warnings or engine lights that appear beforehand which is extremely concerning and a liability. Hyundai motor company is corrupt. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
